The idea is to allow the C++ layer to run arbitrary scripts
as the main script. This paves the way for
- cctest of the execution of Node.js instances
- Earlier handling of per-process CLI options that affect
execution modes (those usually do not make sense for the
embedders).
- Targets like mkcodecache or mksnapshot.
Also moves the handling of `_third_party_main.js` into C++.

This patch:
- Moves `tryGetCwd`, `evalScript` and `fatalException` from
`bootstrap/node.js` into `process/execution.js` so that
they do have to be passed into the worker thread
setup function, instead the worker code can require them
when necessary.
- Moves `setUncaughtExceptionCaptureCallback` and
`hasUncaughtExceptionCaptureCallback` along with the two
global state `exceptionHandlerState` and
`shouldAbortOnUncaughtToggle` info `process.execution.js`
as those are only used by the fatalException and these
two accessors as one self-contained unit.

there is no point in handling the JS error occurred during bootstrapping
by ourselves, we should just crash or let the VM handle it.

This patch refactors the branches for choosing the mode to run
Node.js in `internal/bootstrap/node.js`. Instead of inlining the
decision making all in `startup`, we create a `startExecution()`
function which either detects and start the non-user-code mode,
or prepares for user code execution (worker setup, preloading modules)
and starts user code execution.
We use early returns when we decide the mode to run Node.js in for fewer
indentations and better readability.
This patch also adds a few comments about the command-line switches
and a few TODOs to remove underscore properties on `process` that
are mainly used for bootstrap mode branching. It also includes
a few other refactoring such as inlining functions/variables
that are not reused and removing the default argument of
`evalScript` for better clarity.

previously.
Simplify unhandled & handled rejection tracking to do more in C++ to
avoid needing to expose additional info in JS.
When new unhandledRejections are emitted within an unhandledRejection
handler, allow the event loop to proceed first instead. This means
that if the end-user code handles all promise rejections on nextTick,
rejections within unhandledRejection now won't spiral into an infinite
